Proscan to Bang and Olauffson sound system

FDirstly, you should not connect your TV to a Sound System. If you desire to listen to your Broadcast TV , and enhance the listening experience,I suggest you use the Audio L & R outputs of your Cable Box to your Sound System AUX IN , and Video Out to the TV's Video IN socket. Then you will recieve a better picture and a enhanced sound quality. But just directly connecting the TV's Audio Out to the Sound System will make scarcely any difference.
